Key to All Optical Illusions Discovered
Key to All Optical Illusions Discovered
Humans can see into the future, says a cognitive scientist. It's nothing like the alleged predictive powers of Nostradamus, but we do get a glimpse of events one-tenth of a second before they occur. And the mechanism behind that can also explain why we are tricked by optical illusions. Researcher...
Life Endures 120,000 Years Under Ice
Life Endures 120,000 Years Under Ice
Being tiny has its advantages, and a newly discovered microbe in Greenland has exploited this fully. The bacterium survived more than 120,000 years beneath the ice where inhospitable conditions reach new lows. Most organisms constantly deal with trade-offs, such as some hot-desert residents that take advantage of sunshine yet must...

New Fossils Suggest Ancient Cat-sized Reptiles in Antarctica
New Fossils Suggest Ancient Cat-sized Reptiles in Antarctica
Cat-sized reptiles once roamed what is now the icebox of Antarctica, snuggling up in burrows and peeping above ground to snag plant roots and insects. The evidence for this scenario comes from preserved burrow casts discovered in the Transantarctic Mountains, which extend 3,000 miles (4,800 km) across the polar continent...

How Stress and Diet Cause Heart Attacks
Word of Tim Russert's death at 58 shocked many Americans today, and behind the grief came nagging questions about heart attacks, like the one that struck the newsman, and anxiety about how they kill. Russert's death came in a week when the government reported U.S. life expectancy had risen to...
San Andreas Fault Longer Than Thought
San Andreas Fault Longer Than Thought
As if the San Andreas Fault weren't long and menacing enough, newly found mud pots and mud volcanoes now suggest it extends another 18 miles, going under the Salton Sea and beyond, in the desert southeast of Palm Springs. The extension is probably inactive. U.S. Geological Survey researchers David K....
How Early Experimenters Developed the Bow & Arrow
How Early Experimenters Developed the Bow & Arrow
Technology doesn't just advance on its own. Somebody has to try new things, experiment, innovate, and test it all again and again. The same was true 1,500 years ago when the bow and arrow was introduced to North America, a new study suggests. University of Missouri archaeologists have discovered that...
